noise loading meaning in English
噪声负载
Examples
- In first part of the thesis , by a review of the research on aircraft sonic fatigue , the formulas for calculating natural frequencies of the typical aircraft skin - panel structure with four edges simply - supported or four edges fixed - supported were drawn , the response of displacement and stress was analysed under the condition of random white noise loading with the steady - state or unsteady - state . the procedure how to use data of s - n curve under constant loading for predicating the fatigue life of skin - panel subjected to random loading was shown
通过对声疲劳问题研究的回顾，根据典型飞机蒙皮壁板模型，整理了四边固支，四边简支两种边界条件下多阶模态固有频率，非平稳及平稳随机白噪声载荷下的位移和应力响应，以及如何从等幅s ? n曲线求得随机载荷应力下的疲劳寿命。
